Product Features

Deep indigo blue Tosa washi paper “victory colour” dial with gold-coloured accents.

Washi paper has long been used for paper screens in Japan to bring natural light into living spaces, making it the ideal material for Eco-Drive watch dials. Its distinctive appearance and texture reflect Japanese aesthetics that have been handed down over countless generations.

Kachi-iro is a traditional deep shade of indigo that is considered lucky because it is pronounced in the same way as the word for “victory colour.” The colour was often used on samurai armor and celebratory gifts due to its association with victory. The washi paper on the dial was hand-dyed using a traditional technique known as natural lye fermentation dyeing. The dye is fermented and applied multiple times, creating a shade of indigo with incredible depth. The appearance of the delicate washi paper changes subtly depending on the angle and intensity of the light striking the dial. The CITIZEN logo, Eagle Mark, and hands on the dial are finished in an eye-catching gold colour. The crown and the Eagle Mark on the case back also feature the same appealing gold hue. These sophisticated accents are exclusive to this limited-edition model.

■ Super Titanium™ case

CITIZEN’s proprietary Super Titanium™ is the ideal material for watches - it is lightweight (approx. 40% lighter than stainless steel) with superior hardness (approx. 5 times harder than stainless steel), as well as being corrosion resistant and gentle on the skin. The case and bracelet are treated with Duratect Platinum*4, giving the metal a gleaming, almost transparent silver hue that stays beautiful for longer. The lugs and the bezel feature a highly polished mirror finish while the bracelet has a brushed finish to create an attractive contrast.

■ The eagle mark - the symbol of The CITIZEN

The dial, crown, and case back feature eagle marks - the symbol of The CITIZEN. Eagles have incredible eyesight – they can clearly spot their prey from a distance of 1,000 meters or more. The eagle symbolises foresight, the ability to anticipate the future and act accordingly. Eagles have also formed bonds with humans since ancient times. The eagle mark symbolises the twin ideals of The CITIZEN - foresight and dedication to the pursuit of ideals as well as the enduring connection between watch and wearer.
